Q. We are currently writing a protocol for conducting a process validation activity for our cleaning procedures for metal parts after our machining manufacturing process. What are the differences between cleaning effectiveness of Alconox detergent for cleaning various metallic surfaces such as stainless steel, titanium and cobalt chrome? Also, does Alconox detergent effectiveness change based on contamination characteristics, surface geometry or any other factors?

In addition to detergent choice, there are several factors that are responsible for cleaning effectiveness. We offer an acronym to help clients keep each of these variable top of mind — “BATHOCARD.” Here are the factors and variables that influence cleaning outcomes:

Before – handling prior to cleaning

Agitation – type of movement used to enhance cleaning

Time – duration of cleaning cycle

Heat – temperature of cleaning solution

Orientation

Cleaner – chemistry of cleaning solution

After – post cleaning handling

Rinse

Drying

It is important to understand and control these interrelated cleaning variables and understand how they influence critical cleaning. Details about how to better understand the influence these variables are available in our Critical Cleaning Guide.

In short, contamination characteristics, surface geometry and other factors may influence cleaning characteristics. As it always seems to be, the details are critical. We are pleased to discuss your particular application in detail.
